For J&T for Shopee return is FOC, if branch charges u ask for receipt complaint to Shopee they will give u free voucher as compensation.
For other courier for Shopee return ownself have to print.

For Lazada return all courier u have to ownself print. If u print at branch sure have to pay.

Which courier? If pickup some courier allow.
But for Ninjavan, J&T and Poslaju sure have to ownself print.

should be a reliable brand i guess. i know of this brand from a shop at the IT mall. the shop person told me that it is a brand that is even earlier than xiaomi for powerbank.

i did not buy it from him though becos i realise that shopee yoobao store is selling cheaper.
and importantly, he even opened the sealed package of the powerbank to show me the item and try the fast charging even though i did not even request that. i even tot him not to open but he insisted to open.

then i was wondering, if i do not buy it, are u going to sell this opened item to the next customer as brand new item?
or the one i am about to buy from u was actually an item that you had done the same thing to a previous customer?
